Answer this question truthfully
### Question: What are the symptoms of Hepatocellular adenoma?
### Response: Abdominal pain is the most common presenting symptom in some patients, and the pain is usually related to tumoral hemorrhage. Right upper quadrant abdominal fullness or discomfort is present in 40% of cases due to mass effect. Eventually, spontaneous rupture or hemorrhage may occur, leading to acute abdominal pain with progression to hypotension and even death. Patients with hepatocellular adenomas typically have a history of oral contraceptive use (females) and long term anabolic steroids use (males).
